3.3V Small-Form-Factor (SFP) Bi-Directional  
transceiver module designed expressly for  
high-speed communication applications that  
require rates of up to 1250Mbit/sec. It is  
compliant with the Gigabit Ethernet and Fast  
Ethernet standards, as well as the SFP  
Multisource Agreement (MSA).

Gigabit Ethernet/ Fast Ethernet  
FTTx WDM Broadband Access  
The SPBD-1250xxxx transceivers provide with  
the LC receptacle that is compatible with the  
industry standard LC connector. The transceiver  
is also compatible with industry standard RFT  
connector and cage. It also includes a LOS  
(Loss Of Signal) circuit that provides a TTL  
logic-high output when an unusable optical  
signal level is detected.  
Performance  
SPBD-1250B4Q1RT data link up to 10km in  
9/125um single mode fiber.  
Support industrial temperature operating  
The module includes 1490nm un-cool DFB  
laser, InGaAs PIN, Preamplifer and WDM filter in  
a
high-integrated  
high-density system application. The SFP  
Bi-Directional transceiver can upgrade  
optical  
assembly  
for  
transmission capacity very convenient without  
installing new fibers.

Notes:  
1) Circuit ground is internally isolated from frame (chassis) ground. Tx GND and Rx GND may be internally isolated  
within the TRx module.  
2) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K~10Kresistor on the host board.  
Pull up voltage between 2.0V and VccT+0.3V. The output indicates Low when the transmitter is operating  
normally, and High with a laser fault including laser end-of-life. In the low state, the output will be pulled to less  
than 0.8V.  
3) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module  
with a 4.7 – 10 K resistor. Its states are:  
Low (0 – 0.8V):  
(>0.8, < 2.0V):  
High (2.0 – 3.465V):  
Open:  
Transmitter on  
Undefined  
Transmitter Disabled  
Transmitter Disabled  
4) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K – 10Kresistor on the  
host board. The pull-up voltage shall be VccT or VccR.  
Mod-Def 0 is grounded by the module to indicate that the module is present  
Mod-Def 1 is the clock line of two-wire serial interface for serial ID  
Mod-Def 2 is the data line of two-wire serial interface for serial ID  
5) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10Kresistor.  
Pull up voltage between 2.0V and VccR+0.3V. When high, this output indicates the received optical power is  
below the worst-case receiver sensitivity. Low indicates normal operation. In the low state, the output will be  
pulled to less than 0.8V.  
6) RD-/+: These are the differential receiver outputs. They are AC coupled 100differential lines which should be  
terminated with 100(differential) at the user SERDES. The AC coupling is done inside the module and is thus  
not required on the host board.  
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP  
connector pin. Recommended host board power supply filtering is shown below page. Inductors with DC  
resistance of less than 1 Ohm should be used in order to maintain the required voltage at the SFP input pin with  
3.3V supply voltage. When the recommended supply-filtering network is used, hot plugging of the SFP  
transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value.  
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100  
differential termination inside the module. The AC coupling is done inside the module and is thus not  
required on the host board. The inputs will accept differential swings of 500 – 2400 mV (250 – 1200  
mV single-ended), though it is recommended that values between 500 and 1200 mV differential (250 –  
600 mV single-ended) be used for best EMI performance.
